Hi Greg,
Still no luck on connection drops though I disabled SACK and mtudisc.
I have a question here:
In case of TCP re-transmission I am seeing that length is getting
changed, will that lead to a problem in the first place? Currently my
telnet sessions are getting closed when a re-transmission when a
different length happens. I my opinion is that the packet shouldn't
get changed on re-transmission in any respect, right?
